IMPROVEMENT IN GAUGCOCKS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it muy concern: y

Be it known that l, GEORGE L. WA'rsoN, of Nesquehoning, in the county of Carbon, and State of Pennsylvania, have invented certain Improvements in Gauge-Cocks for Steam-Boilers, of which the ,following is a specification. Nam/re and Qbjcctsof the Invention.

,Thefrst part of my invention relates to thecombinatiou of a cap provided with a stop-screw, and a lgauge-cock stem, iitted with a stop-cock, and provided with a screw and a projecting seating; the object of this part ofguy invention being to permit of cleaning the gauge-cock stein when it becomes obstructed, and of repairing the seating, when it 'may be necessary, without blowing the steam and waterfrom the boiler.

The second part 'of myinvcntion relates to the combination of a cap provided with a hollow stop-cock, and a gauge-cock stem, fitted with a stop-cock, and provided with a projecting screw.; the object of this part ot' my invention being substantially the same as that ofthe first part. It is also intended as a substitute for the 'cap used in the iirst part of the invention, and is to be substituted and used after the seating of the gauge-cock stem has become so worn, from repeated repairs, as to be ineiectual for the purpose for lwhich it was intended.I

Description of the Drawings.

Figure 1 is a longitudinal section of a gauge-cock,

embodying the first part of my invention.

Figure 2 is a detached View of a cap with a stopscrew.

Figurc 3 is a partial sectional view of a gauge-cock,

' embodying the second part of my invention.

Figure 4 is a detachedview ofthe cap with the hollow stop-cock.

General Description.

c is a gauge-cock stem.

b is a stop-cock, itted in the same.

c is a cap, which iS screwed over the eud ot" the. gauge-cock stem a..

d is a stop-screw, used with the cap c.

e e is the seating ofthe gauge-cock stem a.

The point of the screw d meets the seating e e, thereby closing the opening f in the gauge-cock stem a.

g is a cap, provided with a hollow stop-cock, 71., which is screwed over the end ofthe gauge-cock stem a, and is used in the second part of my invention.

,Operationof the Invention. The gauge-cockstem a, fitted with the stopcock b,

and provided wit-h the seating-e e, and the cap` c, provided with the stop-screw d, operated in combination, compose the lirst part of my invention.

The stop-cock bis usually lett open.

When it becomes necessary to clean the gauge-cock stem a, or to repair the seating e e, the stop-cock b must be turned so as to shut od' the steam and water. The cap c may then be removed, which'enables one to get at theopening f in the gauge-cock stem a, .or at the seating e c. l

If the opening f be obstructed,.the stop-cock b may be turned open, and the obstruction removed by running a wire through the opening f.

As soon as the steam escapes, or the water flows, the stop-cock b can be closed. y

By shutting ofi' the steam and -water with the stopcock b, and removing the cap c, the seatinge e-.can'be .repaired at any time.l i

The seating e e is so constructed that it will admit of repeated repairs, as also is the point of the screw d. Either of them can be repaired, until they are worn to the threads'of the screws iioxn which they project. When the seating e e, and the point of the screw d can no longer be repaired, the cap c may be discarded and the cap g, provided with the hollow stop-cock h, may be substituted inrits stead. v

The cap g, provided with the hollow stop-cock h, and the gauge-cock stem 'a, itted with the stop-cock b, operated in combination, compose the second part of my invention.

The gauge-cock stem c may be cleaned in the same manner as in the first part of my invention, when the cap cis used.

C' latins.

-I claim, as my invention-- 1. The gauge-cock stem a., `providedwith the stopcock b, and having a projecting seating, e e, adapted for use'in connection with the cap c and stop-screw d,

iu the manner and for the purpose specified,

2. The cap g, provided with the hollow stop-cock h, when said cap is adapted for use upon the gauge-cock stem a, tted'with the stop-cock b, with Aor without the seating e e, all in the mannen' and for the purpose specified.

In testimony that I claim the foregoing improve ment in gauge-cocks for *steam-boilers, as above de-` scribed, I have hereunto set m'y hand andseal, this.A
